INSOLE-CHAYNNELIVNQAN'D LIP-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 656,842, dated August 28, 19 00.

Application filed December 2, 1899. Serial No. 738,962. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT E. JOHNSON, of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Insole- Channeling and Lip-Setting Machines, of which the following, taken in connection with the accompanying drawings,is a specification.

My present invention relates to insole-channeling and lip-setting machines, and is an improvement upon the invention shown and described in Letters Patent No. 638,394, granted to the Economy Machine Company December 5, 1899; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the accompanying drawings and to the claims hereto appended and in which my in- Vention is clearly pointed out.

Figure 1 of the drawings is a plan of a machine embodying myinvention. Fig.2 is a front side elevation. Fig. 3 is an end elevation. Fig. 4 is a vertical section on the irregular line a; on Fig. 1. Fig. 5is an inside elevation, partly in section, of the channelcutting tools, their stocks, and the horizontally-reciprocatin g slide in which said stocks are mounted. Fig. 6 is a elevation of the same parts looking at the left side of Fig. 5. Fig. 7 is a transverse section on line y g on Fig. 6. Fig. 8 is an elevation of the lip-setting-hammer lever and showing a portion of the frame and the upper end of the hammeroperating rod in section. Fig. 9 is an inverted plan of a portion of the working end of said hammer. Fig. lO is an end view of said hammer looking at the right hand of Fig. 8. Fig. 11 is a transverse section of an insole of the style to be channeled by my invention.

In the drawings, 1 represents the base of the head of the machine, having formed in one piece therewith or secured thereto the columns 2, 3, 4, and 5 and the upwardly-pro jecting plate 6. A bracket, comprising the parts 7, 8, 9, 10, and 11, is mounted and movable vertically in the column 2 and held normally in contact with the upper end of said column by the spring 12, and said bracket is "movable vertically by the hand-lever 14, as

shown in Figs. 2 and 4.

1'? is the cam-shaft, 18 a cylinder-cam, and 1,9 and 20 are cam-disks mounted upon said shaft, and 21 is the hand or driving wheel for imparting motion to said shaft in the direction indicated by the arrow on Figs. 3 and 4.

The bed 1 is mounted upon the column 22, a portion only of which is shown in Figs. 2, 3, and 4, andupon which the lever 14 is mounted, as shown.

The plate 10 has mounted therein so as to be movable horizontally therein the stand 23 24, which is held in place in its bearings in plate 10 by the cap-plates 25 and is moved toward and from the front of the machine through the medium of the eccentric-pin 26 28 29, the block 30, the lever 31, and the campath formed in the periphery of the cylindercam 18, as shown in Fig. 1. The stand 23 24 has mounted therein the tool-stocks 32 and 33,which are pressed downward by the springs 39 and 40, respectively. The stock 32 has secured to its lower end the cutter 41, one cutting edge 15 of which extends in a horizontal plane parallel with the driving-shaft and another cutting edge 16 extends at right angles to and in the same vertical plane as said cutting edge 15, said cutter serving to reduce the portion of the sole outside of the channel to an even thickness, cutting away only so much of the flesh side of the leather as is necessary to that end, and the vertical outer side of said cutter 41 also serving as an abutment or anvil againstwhich the outer surface of the channel-lip is pressed when its other side is struck by the lip-setting tool, thereby limiting the inward movement of said lip and insuring a uniform action of the setting-tool upon said lip. The stock 33 carries at its lower end the cutter 46, the cutting edge of which is slightly inclined to a hori zontal plane that is parallel to the drivingshaft and lies in a vertical said driving-shaft, as shown. 43 and 49 are pendent arms carried, respectively, by the stocks 32 and 33 and which press upon the solo in front of the cutters 41 and 46 and clamp it between their lower ends and the work-supporting disk 51, carried by the stand 52, as shown. 7

The hub 7 of the tool-carryin g bracket has adj ustably set therein the bushing 62,in which is mounted loosely the forked stud 64,to which is pivoted the lever 65, to which a vertical vibration is imparted by the cam-path 66, (shown in dotted lines in Fig. 4,) acting upon the lever 67, connected at its movable end by the link 69 to said lever 65 at 71, as shown, and a lateral vibration is imparted to said lever 65 by means ofacam-path (not shown) in the cam-disk 20, acting upon the lever 74, connected at its movable end by the link 73 to the right-hand end of said lever 65. The lever 65 has connected to its left-hand end by a ball-and-socket joint the upper end of the feed-plate 79, to the lower end of which therefor, and that the pendent arms 43 and 49 press directly upon the solewithout the intervention of revolving rolls.

A lever 53 is pivoted to the stand 52 by its rear end and has secured to or formed in one piece therewith directly at the right of the center of the work-support, as seen in Fig. 2, the gage 60, which projects over the upper surface of the work-supporta greater or less distance, according to the adjustment of the lever 53, which in this application is accomplished as 7 follows: The lever 53 has adjustably pivoted to its front end one end of the link 54, the opposite end of which is provided with a slot 55, through which passes the stud 56, set in the fixed stand 57, and upon which is mounted the segment 59, carrying the lever 58, the

eccentric or cam path of which segment acts upon a truck mounted upon the pin 61, set in the under side of the link 54. The stand 57 has formed about its front edge the upwardlyprojecting segmental lip 63, in the upper edge of which is formed a plurality of detentnotches 68, 70, and 72, into which the inner end of locking-lever is forced by the spring 76 to lock said gage in its adjusted position, the object of this adjustment of the gage being to vary the distance of the channel from the edge of the sole in different parts of the same sole, as wide in the shank, narrower around the inside of the fore part and around the toe, and narrower still on the outside of the fore part or ball of the foot. The pivotal pin by which the link 54 is connected to the lever 53 is adjustable in the slot 76 formed in the left-hand end of said link, as shown in Fig. 1, to uniformly increase or diminish the distance between the edge of the sole and the channel.

The channel-forming cutter 46 is provided just in the rear of its cutting edge with a curved or plowshare-like surface which serves to turn the channel-lip upward into anearlyperpendicular position or at right angles to the surface of the sole. In order to set the channel-lip in said upturned position preparatory to sewing the welt thereto, I mount upon a fixed fulcrum-pin set in the stand 103 the lever 102, having a longitudinal slot 77 cut through it to receive said fulcrum-pin, upon which it may be moved to a limited extent in substantially a horizontal direction, while it may also be vibrated slightly about said pin. The left-hand end of said lever has formed thereon the hammer-head 104 of the general outline shown in Figs. 8, 9,

and 10, including the downwardly-projecting lip 80, having its lower end and inner edge rounded, as shown. The right-hand end of the lever 102 has set therein a stud 81, upon which is mounted a truck 82, (shown in dotted lines in Fig. 8,) and said lever also has mounted on its right-hand end the grooved block 106, which, with the lever 102, projects through a slot 107in link 108, the upper end of which has a bearing in the stand 109, secured to the hub 7, and the lower end of which is pivoted to the front end of the lever 110, the rear end of which is pivoted to the stand 111 and carries near the middle of its length a cam-truck which is acted upon by the campath 112, as shown in Fig. 4, to impart to said link 108 two pairs of rapid vertical reciprocations with a standstill or period of rest between each pair of reciprocations, as shown. The upper end of the slot 107 has fitted therein the forked end of the slotted arm 113, to which the grooved block 106 is adj ustably secured by the screw 114, and a block of leather 115 is inserted in the fork of said arm 113, between it and the upper end of said slot 107, to act as a cushion to deaden the blow when the link 108 is moved downward, and the lower end of said slot 107 has set therein the coiled spring 116, the upper end of which rests against the under side of the block 106 and yields to permit a still further upward movement of the link 108 after the downward movement of the hammer-head 104 has been arrested by any suitable stop, such as the fork of the plate 113 coming in contact with the stand 109.

So far the construction of the lever 102 is substantially the same as in said prior application except the slot 77 formed therein; but in order to accomplish the result desired in this applicationviz., to strike a horizontal blow upon the inner surface of the partiallyupturned lip of the channeled sole-I attach to the front side of the slotted upper portion of the link 108 the cam-plate 83, provided with the inclined slot 84, which receives and acts upon the truck 82, carried by the lever 102 to impart a quick movement of the lever 102 toward the right of Figs. 1 and 2 at each upward movement of the link 108, thereby causing the lip 80 to strike a sudden blow upon the inner face ofthe upturned lip of the sole to firmly set it in said upright position. The block 106 is constructed,arranged,

, and operates substantially as in said prior application.

The operations of the lip-setting mechanism and the gage-adjusting devices will be readily understood from the foregoing without further description here, and the operation of the other parts of the machine are substantially the same as described in said prior application except that the cutter 41 instead of slitting the edge of the sole and turning the upper portion of said slitted edge upward toward the center of the sole, as in said application, simply cuts away any surplus stock necessary to reduce the edge of the sole to a uniform thickness, and the cutter 46 is provided with the curved or plowshare surface arranged to turn the channel-lip upward and outward or toward the outer edge of the sole and no transverse slits are cut in the upper surface of the sole.

I claim- 1. In a machine for preparing insoles, the combination of a lip-opening plowshare; a vi- I brating and endwise-reciprocating lever; a

hammer-head or setting-tool carried by said lever and provided with an operating-lip constructed and arranged to act upon the inner surface of the upturned channel-lip, in a direction parallel to the surface of the sole; means for imparting to said setting-tool a slight vibration toward and from the surface -of the sole, and an endwise-reciprocating movement, in a direction parallel to the plane in which lies the tread-surface of the sole, when being acted upon; and means for intermittently feeding the sole in a direction at right angles or nearly so to the plane of reciprocation of said setting-tool.

2. An insole-channeling machine comprising the following means for setting the channel-lip, viz., the lever 102 provided with the slot 77 and the hammer-lip 80, and mounted upon a fixed fulcrum-pin; the truck 82 carried by said lever; the link 108 provided with the slot 107 in its upper end to receive the inner end of the lever 102; the cam-plate 83 having the inclined slot 84: which receives and acts upon said truck 82 to move said lever 102 endwise; the spring 116 set in the slot 107 beneath said lever 102; and means for imparting to said link 108 a vertical reciprocation.

3. In an insole-channeling and lip-setting machine, the combination of a work-feeding mechanism; a channel-cutting tool provided with means for turning the channel lip upward, a lip-setting tool constructed and arranged to be slightly vibrated toward and from the bottom of the sole-channel, and to be reciprocated in a direction substantially at a rightangle to its vibratorymovement, to

set said lip in a position at a right angle, or nearly so, to the surface of the sole; an abutment in near proximity to said channel-cuttion toward and from said abutment in a direction parallel to the plane in which lies the tread-surface of the sole.

4. In an insole-channeling machine the combination of a work-support; a workfeeding mechanism; a channel-cutting tool, constructed and arranged to cut a channel and turn the channel-lip upward; the lever 53 pivotally connected at one end to a fixed'part of the machine; a gage carried by said lever and projecting over the upper surface of the worksupport; an oscillating cam mounted upon a fixed axis; means connecting said cam with said lever 53; a hand-=lcver connected to said cam for oscillating it; a fixed segmental lip partially surrounding said cam and provided with aplurality of detent-notches 5 and a locking-lever carried by said handlever and constructed and arranged to engage said detentnotches to lock said cam in its different adjusted positions.

5. In an insole-channeling and lip-setting machine, the combination of a work-feeding mechanism; a channel-cutting tool provided with means for turning the channel-lip upward; a lip-setting tool constructed and arranged to be slightly vibrated toward and from said work-support and to be reciprocated substantially at a right angle to its vibrating movement to set the lip in an upright position; a vertical abutment or anvil in near proximity to said channel-cutting tool arranged and adapted to limit the movement of said channel-lip when struck by said settingtool; and means for imparting to said settingtool a slight vibration toward and from said work-support, and a reciprocating movement substantially at a right angle to its vibratory movement.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 18th day of November, A. D. 1899.
